Application filed February 21, 1922. Serial No. 538,818.

To alluwhomtz't may. concern: A post 3, provided intermediate of itsends Be itknown that I, LEONARD E. AsKE, a with two collars 3 -and 3spaced from each citizen of :the United States, residing at other,extends at one end through the cen- Duluth, inthe county ofSt. Louis andState tral aperture of said block 1, andv at the op 5 of Minnesota, haveinvented certain new and posite end through the central aperture ofuseful Improvementsin Electric Vaporizers, said block-2, said collarsextending into the of which I dodeclare the following'to'be a recesses 1and '2 respectively and serving specification. I to space said blocksfrom each other.

-M invention relates to electric Vapor zers Positioned onthe'outer ends,or in the re,

10 and has forits object improvements in the cesses 1 and 2 of theopposed blocks are form andstructure thereof. It consists of contactplates 4 and 5 respectively. Above the structures, combinations andarrangeplate 4, is a nut3 mounted on said post and ments of partshereinafter described and adapted to bear upon said hub or upon aclaimed. washer 3 of insulating material interposed 15 In the drawings,Fig. 1, is a top between said'nut and said plate 4. i plan view ofan'upper spacing block. Fig. Belowsaid plate 5, is a contact .Washer 32, is a central vertical section of said block. adapted to bear uponsaid plate 5, and below Fig. *3, is a top pla-n view of a cover plate.said washer 3 is a nut 3 positioned on-said "Fig. 4, is a centralvertical section of said post and adapted to bear upon said 0cover'plate.

Fig. 11,.is a diagram of the ner tosaid plate 5, whereby the opposite wiring plan of said heating element.ends of said wire are, in effect, connected In *the drawings, 1, is aspacing block of with said opposite plates. inparallel. After insulatingmaterial having plurality of said winding is in position, said groovesare 35 any suitable form of wire passages, as filled with vitreouscement for the purpose grooves'l formed in its periphery. A verofeliminatingspaces where liquid mayco'ltical central aperture 1 is formedin sa d lect and for thepurpose of preventing the block. A recess 1 ispreferably formed in escapeof said wire from said grooves; the upperface of said block concentr c w th Saidheating element is adapted to beinsaid aperture but spaced therefrom in any sertedin a case comprisingah b ,7 a suitable manner as'by a hub 1 formed on cover 7 and attachingflanges 7, 7; which said block. The .lower face of said block case isadapted tobeinterposed at anysuitis concave as at l preferably in themanner able point .in the fuel passage between the of the segment of.acylinder, and is prefercarburetor and power cylinder of explosion ablyrecessed as at l concentric. with said engine, thesflanges 7 and 7 beingadapted aperture. tofbe-bolted .to corresponding flanges formed A'block2 is formed in substantially the on theopposing ends of adjoiningsections same' manner as said block 1, but is reversed of said fuelpassage. But if desired, said in position so thatthe concave surface is'upchamber may be cast integral with the pipe permost. If desired, oneor more vertical forming thethroat ofsuch carburetor or fuel apertures1, 1 may be substituted for an passage, in which caseone or both of saidequal number of said grooves for the purpose attaching flanges may beomitted. Said of more securely holding the hereinafter decase hasanaperture 7 formed therein adaptscribed windings, especially theterminal-s ed to approximately register with the bore 55 thereof. ofsaid fuel passage and with the space he no prevent danger suitablesource tween said blocks 1 and 2, across' which aperture 7 said loopedwire 6, extends.

The cover'7 is of metal and is centrally apertured for the passage ofthe upper end of said post 3, a bushing 7 of insulating material beinginterposed between said post and cover. Said cover has formed thereon orsecured thereto any suitable number of depending contact pieces, as 7adapted to bear upon said plate 1. A nut 3 is positioned on said postabove said cover and is adapted to bear upon said cover or upon washer.7 positioned thereon. Said nut operates to draw said heating element upinto operative contact lWltll said contact piece 7 An insulating mat 8is preferably placed in the bottom, ofsaid chamber to of short circuitsof said heating elementif said post is not lifted clear.

In operation the current flows from any of electricity (not shown) tothe upper end of said post 3, thence through said post and the washer 3and plate 5 to said wire 6; thence, dividing, flows through er 7 tovthewall and flanges and attaching bolts of said chamber; thence to theflanges and walls of said fuel passage, and thence by any 7 suitableelectric conductor (not shown) back to said source.

It is obvious that various changes or 'modifications may be made in mysaid in-' vention within the spirit and scope ofcertain of my claims.

Where I have specified the top of certain parts of my said invention Ido not desire to be understood that said invention must in all cases bepositioned as shown in the drawings, since it may be positionedhorizontally, or at an incline,.or might be inverted, depending incertain cases upon the direction of the adjoining fuel passage.-
